The men's Patagonia Island Hopper Shirt helps you keep your cool whether you’re working your way through the Marquesas or the baggage line at Key West International. Its ultralight blend of moisture-wicking 65% all-recycled polyester and 35% organic cotton provides big-time ventilation and 15-UPF sun protection. It also washes easily with a quick dunk in the sink and dries fast. Made with light-colored fabric to reflect the sun’s rays and a straight hem and side vents for casual, untucked comfort. The oversized drop-in chest pockets (sized for a fly box, passport or both) with mesh vents now feature a larger opening for improved access.
